This type of bit is well known for its wear resistance on soft to medium-hard rock formations (between 55 Mpa to 165 Mpa compressive strength). Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture. Recommended for eliminating hole deviation.
